If you have Mind Manager from Mindjet and have problems having purchased a license to use externally to Mind Manager - as well as via hte functions that are available from Mind Manager itself - you need to do as this user did and alll should be well:
What I did is a deinstallation of PDF-XChange from MM7 first. Then I made a new installation of the PDF-XChange PRO at the same place in the Mindjet folder as it previously was.
Fortunately it seems to me that even the pdf-export-button of MM7 is still working.
If posting files to this forum - you must archive the files to a ZIP, RAR or 7z file or they will not be uploaded - thank you.
